Mutants: Genetic Gladiators from Kobojo is a monster battling/breeding game that looks like it might make a fair number of waves. It's sort of like a combination of monster training games like Pokemon and the battle system from games like Final Fantasy VI, with a really nifty art style and some pretty crazy-looking characters.

As your mutants battle they'll level-up and store up energy that they can use to 'breed' with other mutants in order to (potentially) create stronger fighters. It has a lot of player-versus-player elements to it, but there's also a fair amount on hand for those who'd prefer to avoid fighting other people. There's a pretty hefty collection aspect to it, with most of the available mutants sporting three or four different forms/skins. That's all in addition to the planned monthly rare recipe additions and player tournaments.

Mutants: Genetic Gladiators should be coming to the App Store as a universal release in mid-April, for free.
